Use the attached accessories parts and specified parts for installation. otherwise, it will cause the set to fall, water leakage, electric shock ,fire.

Install at a strong and firm location which is able to withstand the set' s weight. If the strength is not enough or installation is not properly done, the set will drop to cause injury.

Before obtaining access to terminals, all supply circuits must be disconnected.

The appliance must be positioned so that the plug is accessible.

The enclosure of the appliance shall be marked by word, or by symbols, with the direction of the fluid flow.

For electrical work, follow the local national wiring standard, regulation and this installation instructions. An independent circuit and single outlet must be used. If electrical circuit capacity is not enough or defect in electrical work, it will cause electric shock ,fire.

Use the specified cable and connect tightly and clamp the cable so that no external force will be acted on the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection.

Wiring routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will cause heat-up at connection point of terminal, fire or electric shock.

If the supply cord is damaged, it must be replaced by the manufacture or its sevice agent or similarly qualifued person in order to avoid a hazard.

An all-pole disconnection switch having a cintract separation of at least 3mm in a poles should be connected in fixed wiring.

When carrying out piping connection, take care not to let air substances go into refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion and injury.

Do not modify the length of the power supply cord or use of extension cord, and do not share the single outlet with other electrical appliances. Otherwise, it will cause fire or electric shock.

Carry out the specified installation work after taking into account strong winds, typhoons or earthquakes.Improper installation work may result in the equipment falling and causing accidents.

If the refrigerant leaks during installation, ventilate the area immediately.Toxic gas may be produced if the refrigerant comes into the place contacting with fire.

After completing the installation work, check that the refrigerant does not leak.Toxic gas may be produced if the refrigerant leaks into the room and comes into contact with a source of fire, such as a fan heater, stove or cooker.

1installation manual

Be sure to be in conformity with the local, national and international laws and regulations.

Read "PRECAUTIONS" carefully before installation.

The following precautions include important safety items. Observe them and never forget.

Keep this manual in a handy place for future reference.

1. PRECAUTIONS

WARNING

WARNING

The safety precautions listed here are divided into two categories. In either case, important safety information is listed which must be read carefully.

After completing the installation, make sure that the unit operates properly during the start-up operation. Please instruct the customer on how to operate the unit and keep it maintained. Also, inform customers that they should store this installation manual for future reference.

Be sure only trained and qualified service personnel to install, repair or service the equipment.Improper installation, repair, and maintenance may result in electric shocks, short-circuit, leaks, fire or other damage to the equipment.

Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electric shock, fire.

When installing the unit in a small room, take measures against to keep refrigerant concentration from exceeding allowable safety limits in the event of refrigerant leakage. Contact the place of purchase for more information. Excessive refrigerant in a closed ambient can lead to oxygen deficiency.

Failure to observe a warning may result in death.

CAUTIONFailure to observe a caution may result in injury or damage to the equipment.

6. ELECTRICAL WIRING

CAUTION

The air conditioner should use separate power supply with rated voltage.The external power supply to the air conditioner should have ground wiring, which is linked to the ground wiring of the indoor and outdoor unit.The wiring work should be done by qualified persons according to circuit drawing.The fixed connecting lines must equip with at lease 3mm electric shock spacing.A leakage protector should be installed according to the National Standard concerning electrical appliance.Be sure to locate the power wiring and the signal wrings well to avoid cross-disturbance and their contact with connecting pipe or stop value body. Generally, do not twist two wiring together unless the joint is soldered well and covered with insulator tape.Do not turn on the power until you have checked carefully after wiring.

CAUTION

CAUTION

The specification of power as the follow display figure, if the capacity is too small will lead to over heat of the wiring,and cause burning of the machine accident.

The air-gap notch in the circuit breaker is used for insulating the flexible conductor, so that must respond to the related national wire requests to connect to the fixed circuit.

CAUTION

The air-conditioner can connect to the central controller (CCM). Before the operation, please correctly connect the wire and well set the system address and network address of indoor unit.

Please use 3-core shielding wire, and ground the shielding layer.

TO OUTDOOR COMM.BUS

The connecting distance of control box and indoor unit should not more than 5 m. This control box can only connect to R410A refrigerant system. During the installation of connecting pipes, do not let air, dust, or other sundries enter to the piping system. Install the connecting pipe only after the indoor and outdoor units have been fixed. When installing the connecting pipes, it must be kept dry and do not let water enter to the piping system. The connecting copper pipes should be wrapped with thermal insulation materials (the thick should be more than 10mm; the close wet area should be thicken properly).

1) The default system address is “00” for AHUKZ-01, “00” and “01” for system A and B of AHUKZ-02 respectively.

2) If there are several indoor units multi-connected, the system address may be conflict between the different units. In that case, reset the in door unit’s address is needed.

3) If the system address conflict occur, the indoor units must use remote controller to set the system address first (For setting system address to the indoor unit with two or more master boards, it have to use display panel with 10-core wire to connect the display panel, and address setting for every master board respectively).

4) Communicating the indoor and outdoor units to finish setting network address, its address is the same as the indoor unit address, no need to setting separately.

5) When all the indoor units are AHUKZ-01/AHUKZ-02 or V4+ series indoor units, centralized control of indoor unit can finish upside the outdoor unit, no need to do the centralized control inside the indoor unit, the detailed instruction refers to V4+ Outdoor Unit Instruction.

6) For the previous indoor unit centralized control function, can connect to the (X,Y,E) terminals and form centralized control network, at that time no need to set the network address, then also can through the outlay network module, mainboard (CN20) and form a network.

For the same indoor unit, each main board must has different indoor unit addresses and network addresses.

When use centralized controller to control indoor unit, and set address for the AHUKZ-02 with two or more main boards, we suggest that set the neighbor address for the same main board of indoor unit. When use centralized controller for controlling, main board in the same indoor unit must ON and OFF at the same time, for avoiding that affect the usage function of the machine.
